COMPOSED OF BOTTLE car.

To all whom' it may concern:

Be it known that I, ALEXANDER MELDRUM, a citizen of the United States, and residing at Syracuse, Onondagalcounty, State of New York, have invented certain new and useful Improvements in Bottle Caps, of which the following is a specification.

The present invention relates to bottle caps of the type commonlyused in sealing milk bottles. Such bottle caps are made of paper board and many devices have been proposed for lifting or extracting the caps from the bottles without mutilating them so that they may be replaced to protect the remaining Contents, Among such devices there are various forms of wire loops. Some of these loops have'been passed around the edge of the bottle cap, but this results in imperfect sealing of the bottle as the wireusually pr0- jects beyond the margin of the cap. After the cap has -been removed and replaced it is frequently found that'the wire has cut into the edge of the cardboard permitting air to enter and permitting leakage of the contents compactly for shipment and also for usein the capping machines. I

The present invention comprises a lifting device for a cap which device is inthe form of a-loop havingits ends anchored in the cap by passing them from the top to the bottom and then to the top, the ends of the loop being foldedflat upon the cap. By securely anchoring the wire pull inthis manner very thin wire can be used whicli will permit of the caps being closely assembled in cy-,

lindrical packages; In the accompanying drawing the wire is shown exaggerated inthickness for purposes of illustration, but it will be understood that in practice the thickness of the wire used is not Sufficient to materially separate the caps in a package. I fact the wire can be pressed into; the body Application filed July 19, 1921. Serial No. 485,353.

- of the cap'without materiallyweakening the latter.

Referring to the accompanying drawings Fig. 1 is. a plan view of the preferred form Fig. 2 is. Figure 1; Fig, 3 is a section o-n theline 3-3 of Figure'2;'

Fig. 4 is a view. Figure 2; I I

Fig. 5 is 'a section on the line 5 -5 of Figure2; I

enlarged view of a portion of of the reverse side of Fig. 6 illustrates a slightly different modification of the invention; and' 1 W i Fig. 7 is;a section on line 7-7 of Figure 6.

Referrin to the drawings 10; indicates the paper oard disk or cap which may be, of any suitable quality alndll indicates a wire pull. The wire 11 is referably U- shaped and has its ends passed through the cap at 12, then folded back and again passed through to the top' of the cap at 13 and turned down against the top of the cap as at 14.. Porti0ns'14. are preferably directed F outwardly toward the'adjacent margin of the cap. As shown in Figures 1 to 5 the POItlOIlS 15 .of' the wire exposed on the under side of the cap are arranged diagonally, that is,-,they extend rearwardly from the adjacent margin and laterally outward from-theU-s'haped body ofthe pull. This constructiqni-prevents thev ends 14 from interfering' with the pressing of' the 100 .11

against the capand it also anchors the 00p to considerable portions. of the body of the cap between the. points 12 and 13. The points 12 maybe 'ratherclose to the margin of the cap .thus makinglthe strain on the loop "most efi'ectivein removing the cap. It

is found that caps provided w th wire loops anchored as described maybe repeatedly removed and re' laced without tearing the loops from theidisks or mutilating' the disks so as'tocause leakage. 1

In the form shown in Figures (Sand 7 the branches of the loop 11 enter the cap at 16,

are: folded rearward and inward and pass through to the upper side of the cap at 17 the extreme ends being directed forward to the topof the cap as shown at 18. The portions19 of'the wire onthe under side of the cap'aredirected' rearwardly and diagonally toward each other, as shown in Figure 6. The operation of this form of the device is substantally the same as thatfof the form shown in the preceding figures.

It will be evident that my invention may be embodied in a'number of difi'erent forms. It is preferred that the portions of wire exposed on the under side of the cap be arranged at an angle to the axial line of the loop, as shown in Figures 4 and 6,. although it would not be impractical to have them parallel with the legs of the loop as the ends which lie on the upper surface of the cap might be directed inward or outward so as not to interfere with folding the loop-closely upon the upper surface of the cap.

Having thus described the invention what I claim and desire to secure by Letters Patent is:

1. A bottle cap comprising a disk of paper 'board having a wire pull, said wire being in the form of'a loop having its ends passing through the disk within and near the margin thereof from the upper side to the lower side and again passing through from the lower side to theupper side, the extreme ends being folded against the upper face of the cap.

2. A bottle cap comprisin a disk of paper board having a wire pull, said wire being in the form of a loop having its ends passing through the disk within and near the margin thereof from the upper side'to the lower side and again passing through from the lower side to the upper side the extreme ends being folded against the upper face of the cap and the portions of thewire exposed on the under side of the cap being arranged at an angle to the axial line ofthe loop and extending laterally outwardly: from the legs of the loop.

In testimony whereof I hereunto afiix my signature.

ALEXANDER MELDRUM.
